Oracle Database 12c: RAC Administration — Question 41

You administer a three-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1, PDB_2, and PDB_3.
You want to drop PDB_3.
Which two statements are true? (Choose two.)

Answer options

• A. PDB_3 must be closed on all CDB1 instances.
• B. Manually created services for PDB_3 are not removed automatically from the OCR when dropping PDB_3.
• C. CDB1 must be open in restricted mode on all cluster nodes.
• D. PDB_3 must be open READ ONLY in all CDB1 instances.
• E. Manually created services for PDB_3 are removed automatically from the OCR when dropping PDB_3.

Correct answer: A, E

Explanation

The correct answer is A and E. PDB_3 must be closed on all instances before it can be dropped, fulfilling statement A. Additionally, any manually created services for PDB_3 will be automatically removed from the OCR when the PDB is dropped, making statement E true. Statements B, C, and D are incorrect because they do not reflect the necessary conditions for dropping a PDB.
